ARP extended wheel studs

For install on 2015+ Sti, you will need to remove the hubs to get these on. There are four 14mm bolts and the axle nut that need to come off to remove the hub. There is NO way to squeeze these in or cut anything like the brake shield to make them fit without removing the hub on the Sti. Besides a difficult install this product is great.
installed on 05 STI, fronts ez, rears not so much.

alright the front install on this is very simple, hopefully you dont need instructions for that.... onwards to the rear install - not for the feint of heart. so obviously everybody has a "correct way" of doing things, i made mines work and it does triple digit speeds no problems and pulls G's on mountain togue. full disclaimer not responsible if you choose to install it "my way". obviously the stud is long so it wont clear the rear hub assembly any way you stuff it in - short of removing the entire spindle, installing a new wheel bearing and doing it the "right way" heres what you do, or at least what worked for me. remove the brake rotor, remove rear ESP sensor, loosen the ABS tone wheel, remove parking brake shoes, or disconnect the springs and leave it hanging, loosen the backing plate to spindle bolts (4 of them). now you are going to "precisionly grind the outer edge of the wheel stud until it clears the rear ESP sensor hole and stuff it through and properly secure the stud. ship it broskies.
2015 STI ARP Wheel Stud Review
Ice8erg 2 years ago
I picked up 4 packs to use on my 15 STI because after 2 years of AutoX my stock Subaru ones were all starting to crossthread. The rears are a pain to install because they moved the wheel speed sensor to the top of the knuckle so you can't do the old trick of expanding that hole to put them in. I was able to undo the 4 bolts that hold the hub assembly to the knuckle and keep the axel nut on the halfshaft and pull the hub out enough to slip the studs in. They are very nicely made and go well with the Gorilla steel racing lugs I ordered as well. I think they will hold up well with time based on friends who AutoX and have been using these for many seasons.

Just an FYI, the site shows that it does not fit the BRZ / FR-S, but they do. :)
Installed on a 2012 Subaru STI 5 Door

Good Product. Installed these with no problem. Recommend pressing them in using a nice wheel bearing. Keeps from damaging the lug and hub. So far they have been good and make it easier installing different rims/tires. I paired these with the Muteki SR48 Chrome Black Open Ended Lug Nuts 12X1.25. Works great. Nice that you can just see the end of the lug knowing that you have a perfect fit. They look good and feel ok. We rally cross the car hard and haven't broken one yet. Another tip. 4 bolts and you have the hub off. Makes it so much easier than installing while the hub is on the car. Take your time and enjoy the installation. I know we did.

If I have these studs installed on my 08 WRX STI hatchback, while running a 10mm spacer and want to change my wheels to a set where I will not need the spacers, can I still use these studs and will I need to get specific hardware in that situation?
A: Depending on what kind of wheels you choose, you may need to use open-ended lug nuts for these to work.
